Seo Master present to you: We just posted updated terms of service for 5 more APIs to include transparent deprecation policies. This is part of their increased commitment as graduates of
Google Code Labs. As we mentioned in March when we
introduced Labs, each of these deprecation policies states that we'll support each version of the API for a guaranteed length of time from when it's deprecated or a newer version is introduced. While it's 3 years for most, it might be less for some. With this batch of updates, for example, the Checkout API has a policy of supporting old versions for 1 year while all of the others will support old versions for 3 years.
You can see the updated terms for all 5 APIs:
